Fortinet FortiAuthenticator Reviews Summary
Author infoRatingReview Summary
Assistant Manager-Networks at a university with 1,001-5,000 employees5.0I've used Fortinet FortiAuthenticator for five years to securely authenticate admin users, especially for remote and VPN access, and I appreciate its global access, strong logging features, and reliable support, despite minor glitches and lacking AI features.
Presales Consultant4.0I primarily use FortiAuthenticator for its two-factor authentication, which significantly boosts security. While it is only an on-premises solution, unlike some cloud competitors, I find its stability and scalability strong, though customer support can be slow.
Network Engineer at Coop Money4.0I use Fortinet FortiAuthenticator for multi-factor authentication due to its easy deployment and solid GUI, though support could improve. It's stable, scalable, affordable, and ideal for small to medium enterprises, but not preferred for larger organizations.
Senior Network and Security Engineer at Symbol Technologies PLC3.5We deployed Fortinet FortiAuthenticator for a client's authentication on Cisco devices. Its integration capabilities and compatibility with FortiToken and zero trust access enhance security. Migration challenges to OpenStack exist, but overall, it positively impacts security costs.
CTO at Exceed NetSec LLC4.0I use FortiAuthenticator for two-factor authentication, finding it effective once configured correctly, but transferring it after losing a device is challenging and slow. The return on investment is hard to gauge, but it is essential for security compliance.
Head of computer systems at Indian Institute of Space Science & Technology(IIST)2.5We use Fortinet FortiAuthenticator for token-based authentication for wireless access and SSO. The product is cumbersome, requires daily re-authentication, and lacks maturity, prompting us to consider replacing it with Duo. It does not meet our needs effectively.
IT Manager at PTECH4.0I use FortiAuthenticator for authentication systems and identity management, valuing its web filtering feature. I previously used Cisco products and am transitioning to Fortinet. Improvements in ransomware protection integration would be beneficial. Evaluating ROI is still ongoing.
Infrastructure Manager at Scandinavian Highlands Holding A/S4.0I’ve used Fortinet FortiAuthenticator for about two years and found it integrates well with FortiGate products, is scalable, and easy to set up, though the price could improve; overall, I rate it 8 out of 10.
